LID FOR CAR-AXLE BOXES.

SPECIFICATION :forming` part of Letters Patent N0. 644,036, datedFlruary 20, 1900.

Application filed December l, 1899- Serial No. 738,770. (No model.)

T0 @ZZ whom, t ntcty concern,.-

Be it known that I, JOHN W. STEPHENsoN, of No. 520 Euclid avenue,Toledo, county of Lucas, and State of Ohio, have invented a new anduseful Improvement in Lids for Car- Axle Boxes, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure l is a vertical longitudinal section on the line I I of Fig. 2 ofmy improved lid for car-axle boxes. Fig. 2 is a front elevation. Fig. 3is a horizontal section on the line III III of Fig. l. Fig. tis across-section on the line IV IV of Fig. l. Fig. 5 is similar to Fig. l,showing a modified form of lid, beinga vertical longitudinal section onthe line V V of Fig. 7. Fig. 6 is aside elevation of the same. Fig. 7 isa horizontal section on the line VII VII of Fig. 5, and Fig. 8 is across-section on the line VIII VIII of Fig. 5.

The object of my invention is to provide a lid of simple and efficientconstruction which will tit neatly to its seat on the face of thecar-axle box even when the hinge-lug of the box is out of parallel withthe edge of the box.

In Figs. l and 2 of the drawings, 2 represents the car-axle box, havingthe usual hingelug 3. 4. is the pintle or hinge-pin, and 5 is aclosing-arm having hinge-lugs 5 5', through which the pin passes. 6 isthe axle-box lid, which is connected to the closing-arm 5 by a stud 7 onthe arm, whose head fits loosely in an open socket 8 on the face of thelid. The lid is also connected loosely at the hinge portion of the boxto the closing-arm 5 or to the hinge-pin-preferably to the hinge-pin-bylugs 9, `through which the pin passes and which are of larger diameterthan the pin, so as to permit some loose or free motion of the lid. Thespring 10 may be of usual construction and bears at one end upon theclosingarm and at the other end against the face of the lug 3, so thatit exerts upon the closingarm a tension pressing it toward the face ofthe box. When the parts are assembled as above described, the lid willbe held against the box by the closing-arm, and as the lid is connectedloosely both with the closing-arm and the hinge-pin it can accommodateitself 5o to its seat on the box even when the hingepin vby reason ofmalformation or warping of the hinge-lugs is not in proper alinement.

The construction is simple and strong, and

the device as a whole is very efficient because 5 5y of the doublekconnection of the lid-namely, the loose connection of the body portionof the lid with the closing-arm and its loose connection at the hingeportion-for these two connections not only afford sufcient iexi- 6obility to the lid to cause it to seat properly, but at the same timethey hold it sufficiently well to make it steady and to prevent it fromwabbling.

In Figs. 5, 6, 7, and 8Ishowamodication 65 of my invention, in which,instead of connecting the closing-arm to the body of the lid by astudand socket, as above described, the arm may be formed with eyes 7',which engage hooks 8' on thelid, or the eyes may be on the 7o lid andthe hooks on the arm. I also illustrate in these ligures a modied looseconnection of the lid at its hinge end with the closing-arm. In thiscase I form lips ll on the margin of the lid, which Iit over thehingelugs of the closing-arm, being bent inwardly for that purpose. Thisconstruction aords, though in a different form, the same kind of looseconnection as described above with reference to Figs. l and 2.

In order to make the lid dust-proof and otherwise to increase itsefticiency, I provide it with a lip .l2 at its upper margin, which titsacross the top edge of the box, and I also prefer to form lips 13 alongthe lateral edges 85` of the lid, which engage the outer edge of thebox.l I also form on the inner side of the lid a lip 14., which when thelid is closed overjections "l5, which extend on the lid upwardly fromthe lip 14 and serve to prevent the oil 95 from spreading sidewise andrunning out at the corners of the box; and by preference theseprojections are made angular in form.

The lips and projections named in this para graph may be applied to lidsof other construction.

Modiications of my invention will be suggested to those skilled in theart; since Vhat I claim isl. The combination of an axle-box, a lid, anda spring-actuated closing-arm hinged to the box, connected loosely withthe body of the lid and adapted to force the same against its seat, saidlid being also loosely connected With one of the said parts at the hingeportion; substantially as described.

2. The combination with the lid, of a springactuated closing-arm, and astud on the arm fitting an open socket on the lid; substantially asdescribed.

3. The combination of an axle-box, a lid, and a spring-actuatedclosing-arm hinged to the box, connected loosely with the body of thelid and adapted to force the same against its seat, said lid having lugsfitting loosely at the hinge-pin; substantially as described.

4. An axle-box lid have an oil-shedding lip on its inner surface adaptedto lie over the edge of the box and having upward projections to preventspreading of the oil; substantially as described.

5. An axle-box lid having on its inner surface projections adapted toprevent lateral spreading of the oil; substantially as described.

G. An axle-box lid having on its inner surface angular projectionsadapted to prevent lateral spreading of the oil; substantially asdescribed.

In testimony whereof I have hereunto set my hand.

JOHN W. STEPHENSON.
